. As used in this part:
(a) "Story" means that portion of a building included between the
upper surface of any floor and the upper surface of the floor next
above, except that the topmost story shall be that portion of a
building included between the upper surface of the topmost floor and
the ceiling or roof above. If the finished floor level directly above
a basement or unused under-floor space is more than six feet above
grade for more than 50 percent of the total perimeter or is more than
12 feet above grade at any point, the basement or unused under-floor
space shall be considered as a story.
(b) "First story" means the lowest story in a building which
qualifies as a story and which provides the basic services or
functions for which the building is used. A floor level in a building
having only one floor level shall be classified as a first story, if
the floor level is not more than four feet below grade, for more
than 50 percent of the total perimeter, or more than eight feet below
grade at any point.
(c) "Mezzanine" means an intermediate floor placed in any story or
room. When the total area of any "mezzanine floor" exceeds 33 1/3
percent of the total floor area in that room, it shall be considered
as constituting an additional "story." The clear height above and
below a "mezzanine floor" construction shall be not less than seven
feet.
(d) "Grade" means the lowest point of elevation of the finished
surface of the ground, paving, or sidewalk within the area between
the building and the property line or, when the property line is more
than 5 feet from the building, between the building and a line 5
feet from the building.
